Method for determining a point in time within an audio signal, said audio signal having been transmitted from a broadcast station to a client and to a server, comprising: deriving, at the server, first signature data (E1, E2,...) from said audio signal, wherein a reference point in time is associated with the beginning or end of the audio data corresponding to said first signature data; deriving, at the client, second signature data (E1', E2',...; ET; ST) from said audio signal, wherein said second signature data are derived in the same manner as said first signature data at the server; comparing said first and second signature data; determining said point in time (T) to be equal to said reference point in time depending on a result of said step of comparing.
